Hello everybody,

I have to configure RIP over ISDN between R4 and R5. R5 receivce and accept
the R4's updates. R4 receives but it doesn't accept the R5's updates. "debug
ip rip events" shows the following:

02:47:15: RIP: ignored v2 update from bad source 139.1.45.5 on Dialer4

Maybe the problem is that R4 gets the IP address from IPCP negotiation (it
sounds estupid, but it's the only difference between R4 and R5 config).

Here are the configs:

R4:
interface BRI0/0
no ip address
encapsulation ppp
dialer pool-member 4
isdn switch-type basic-ni
isdn spid1 51055580000001 5558000
isdn spid2 51055580010001 5558001

interface Dialer4
ip address negotiated
encapsulation ppp
dialer pool 4
dialer remote-name Rack1R5
dialer callback-secure
dialer idle-timeout 0
dialer string 5557000 class CALLBA
dialer string 5557001 class CALLBA
ppp callback accept
ppp authentication chap

router rip
version 2
timers basic 3 18 18 24
redistribute connected metric 2 route-map CON2RIP
network 139.1.0.0
network 150.1.0.0
no auto-summary

R5:
interface BRI0/0
no ip address
encapsulation ppp
dialer pool-member 5
isdn switch-type basic-ni
isdn spid1 51055570000001 5557000
isdn spid2 51055570010001 5557001
isdn calling-number 5557000
no peer default ip address

interface Dialer5
ip address 139.1.45.5 255.255.255.0
encapsulation ppp
dialer pool 5
dialer idle-timeout 3
dialer string 5558000
dialer string 5558001
dialer watch-group 2
peer default ip address pool TEST
ppp callback request
ppp authentication chap

ip local pool TEST 139.1.45.1 139.1.45.4
!
router rip
version 2
timers basic 3 18 18 24
passive-interface default
no passive-interface BRI0/0
no passive-interface FastEthernet0/1
no passive-interface Dialer5
no passive-interface Loopback0
offset-list 0 in 2 Dialer5
network 139.1.0.0
network 150.1.0.0
default-information originate route-map ZERO
no auto-summary

I hope somebody could help me.

Thansk for everything.
